Abstract
The present invention discloses a closure device having a proximal end and a distal end, introduced into a blood vessel, comprising at least two pre-shaped hollow tubes having a proximal end, substantially at said proximal end of said closure device and a distal end, adapted to be introduced from said distal end of said closure device into said blood vessel; wherein, upon deployment of said two pre-shaped hollow tubes within said blood vessel, said distal ends thereof are adapted to (i) engage into mechanical contact, such that a suture being threaded through at least one of said pre-shaped hollow tube can be extracted from the second pre-shaped hollow tube.

A closure device, comprising:
- a proximal end and a distal end, interconnected by a main sheath;
- at least two pre-shaped hollow tubes, each pre-shaped hollow tube comprising a proximal end positioned substantially at the proximal end of the closure device, and a distal end configured to be at least partially deployed from the distal end of the closure device into a blood vessel;
- wherein upon deployment of the distal ends of the at least two pre-shaped hollow tubes into the blood vessel, the distal ends of the at least two pre-shaped hollow tubes are configured for engagement therebetween, to enable threading of a suture from a first tube of the at least two pre-shaped hollow tubes to a second tube of the at least two pre-shaped hollow tubes.
A method for applying a suture to a blood vessel using a closure device comprising a proximal end and a distal end interconnected by a main sheath, and at least two pre-shaped hollow tubes each comprising a proximal end and a distal end, the method comprising:
- deploying the distal ends of the at least two pre-shaped hollow tubes from the distal end of the closure device and into the blood vessel, until the distal ends of the at least two pre-shaped hollow tubes assume a curved shape and engagement is established therebetween;
- and
- threading a suture from the proximal end of a first tube of the at least two pre-shaped hollow tubes to the proximal end of a second tube of the at least two pre-shaped hollow tubes, through the engaged distal ends of the at least two pre-shaped hollow tubes.
